| 요약2 | In Korea, floor impact sound performance evaluation is performed through bang machine, rubber ball and tapping machine. As for the rubber ball, which is heavy &soft impact source, the operator is measuring the performance by free-falling from 1m, so there are concerns about the deviation in the result value. Therefore, a study was conducted to understand the experimental accuracy of the rubber ball that may occur during field measurement, and this study was conducted to analyze the repeatability and reproducibility of the rubber ball under field conditions. As a result of the repeatability test of the rubber ball, there was a difference of less than about 1.2 dB in the measured results for each operator. In addition, the standard deviation of 0.5 dB below 400 Hz occurred in the test results of the same operator. A standard deviation of 0.7 to 2.4 dB occurred in the frequency band above 400 Hz. As a result of the reproducibility test, there was about 1 dB of deviation for each institution depending on the measuring equipment and analysis method. Therefore, it is judged that is necessary to minimize the influence of external noise and to present clear setting conditions for measurement equipment and analysis methods in order to perform on-site measurement on the rubber ball more accurately. |
